The Postal Service, whose reunion at Coachella after a 10-year hiatus was one of the festival's most anticipated performances, has added a San Diego date to its rapidly expanding reunion tour. Many of the previously announced shows on the tour have sold out.

The brainchild of Jimmy Tamborello and Death Cab For Cutie's Ben Gibbard, The Postal Service will perform July 21 at the SDSU Open Air Theatre. Rilo Kiley singer Jenny Lewis will be on board for the SDSU date and the entire tour. She was featured on the duo's 2003 debut album, "Give Up," and on the recently expanded 10th anniversary reissue of the album.

As of this writing, the July 21 SDSU concert by The Postal Service does not appear on the website for the venue or for Ticketmaster. Pre-sale tickets go on sale Wednesday, April 24, at 10 a.m. via The Postal Service website.

Tickets for the general public go on sale Friday at 10 a.m. at all Ticketmaster outlets, online at ticketmaster.com and by phone: (800) 745-3000. Tickets are priced at $23.50 to $49 each, plus service charges.
